With
more than 5 million inhabitants in the metropolitan area, Toronto is the
largest city in Canada.

TTC
(Toronto Transit Commission) operates three full metro lines (1495 mm
gauge) and one short light rail type line (Scarborough RT). Apart from
these rapid transit rail lines there is an 82 km long streetcar
network as well as the GO Transit suburban rail service connecting with
the metro at the central Union station and other stations. Additional
line numbers were first introduced in March 2014. A special airport service,
the Union Pearson Express, was brought into service on 6 June 2015.

The
19 km Eglinton Crosstown LRT [5],
now under construction, will include a 9.8 km underground section. The
new line will be operated with low-floor vehicles and run mostly along
Eglinton Road (2020). (Official
